Has it really been 20 years since we've been scared out of the water? Every summer the Discovery Channel takes to the high seas with one thing in mind: show us sharks. Shark Week has been their most popular feature. In this special collection, 14 of the best programs offered in the last 20 years of Shark Week are presented. You won't be able to look away from such shows as "Shark Attack Rescuers," "Shark Attack Survivors," "Anatomy of a Shark Bite," and "Prehistoric Sharks." You'll definitely rethink your next swim in the ocean after watching Shark Week.
